Chronographs?

[cavelamb]

Got a chrono you like?
Or one you don't?

I have a pair of Competition Electronics Pro-Chrons that work well.
But my buddy has a Lab Radar, and I lust after it.

Never used my deluxe Caldwell. Had it about six years.

Technically, the only thing a shooting chronograph can tell you is how fast your bullet was traveling when it passed by the photoelectric cells. However, this velocity is very important information, because it helps you determine other important data points related to internal, external, and terminal ballistics. It’s not uncommon for actual velocities to be very different from advertised velocities; I’ve seen differences as high as 250 fps with centerfire rifle cartridges. The only way you can make accurate ballistic calculations is to know a load’s actual velocity from your firearm. And for that, you need a chronograph. Here are five things you can glean from that information that can make a real difference in your shooting.

I have a Caldwell, and it’s a pain to use. It doesn’t like sunshine. I’m currently building a black box to keep it in shadow.

I have a Caldwell V1 + the LED Kit.
Works like charm, also in sunlight.
I would love to get their Version 2, where it has been turned upside down.

But if I Upgrade, I think I will look at the new FX TRUE BALLISTIC CHRONOGRAPH

If I ever upgrade it will be to LabRadar.

The buy-in is steep, but you get what you pay for.
This time anyway.

I've had a (now discontinued) Shooting Chrony Beta Master since 2007.

I ordered spare diffusers screens etc, so I should be able to keep it usable a few more years. It's been a good reliable machine.
